Double-beam laser synchronous welding method for titanium alloy wallboard and rib strip through T-shaped joint

Abstract

The invention relates to a laser processing method and in particular to a double-beam laser synchronous welding method for a titanium alloy wallboard and a rib strip through a T-shaped joint. The titanium alloy wallboard is fixed on a movable worktable through a positioning and supporting seat, wherein the rib strip is perpendicularly arranged on the titanium alloy wallboard and is tightly pressed through a tooling fixture; the T-shaped joint is formed by the rib strip and the titanium alloy wallboard; two sides of the T-shaped joint are synchronous welded through a first laser welding device and a second laser welding device. By virtue of the method, the two sides of the T-shaped joint can be synchronously welded by using two beams of laser; the welding efficiency is improved; the purpose of molding at a time can be achieved.

Description

technical field [0001] The invention relates to a laser processing method, in particular to a double-beam laser synchronous welding method for a titanium alloy wall plate and a rib T-shaped joint. Background technique [0002] In aviation products, a large number of sheet metal structural parts use titanium alloy materials. Welding titanium alloys by traditional welding methods is not only difficult to guarantee welding quality but also inefficient, especially when welding large-scale structural parts, the welding quality is even more difficult to guarantee. Therefore, the welding technology of titanium alloy structural parts has become a key problem to be solved urgently. [0003] At present, there is no mature equipment and technology for laser welding of T-joints of integral wall panels, and ordinary riveting or resistance penetration welding has been used, which cannot meet the design requirements of high strength, super maneuverability and excellent stealth performance ...

AI Technical Summary

Problems solved by technology

[0003] At present, there is no mature equipment and technology for laser welding of T-joints on integral wall panels, and ordinary riveting or resistance penetration welding has been used, which cannot meet the design needs of high strength, super maneuverability and excellent stealth performance of the fuselage

Many of the existing laser welding equipment are mainly aimed at the general-purpose laser platform for laser welding, cladding and composite welding. They are not special equipment for welding long-sized integral thin-plate T-joints, so this problem has not been completely and effectively solved.
